DONFL
78yoMultimodal imaging analysis in a a case of Dissociated Optic Nerve Fiber Layer (DONFL) appearance after internal limiting membrane peeling for idiopathic macular hole. The DONFL appears after vitrectomy, showing as slit-like, arcuate defects in the retinal nerve fiber layer, particularly visible using Optical Coherence Tomography (OCT). The analysis through different color channels enhances visualization, aiding in distinguishing these alterations from other retinal pathologies. Understanding the impact of color channel adjustments is critical for accurate assessment and documentation of DONFL in post-surgical patients.
Disclosure: All images featured in this post were acquired and analyzed using devices integrated within the Zeiss Retina Workflow. This ensures high-quality, detailed visual data for comprehensive assessment.

Macular telangiectasia type 2
82yoIn Macular Telangiectasia (MacTel), blue light reflectance imaging is effective for identifying early retinal changes. It enhances the visualization of macular pigment loss and plexiform layers abnormalities before identifiable using other imaging modalities. This non-invasive technique is invaluable for detecting and monitoring MacTel in its initial stages. #MacTel #BlueLightReflectance #EarlyDetection […]

Epiretinal membrane
64yoEpiretinal membrane (ERM) with ectopic inner foveal layers (EIFL) represents a more advanced stage of ERM development. EIFL is characterized by the abnormal extension of inner retinal layers across the fovea, disrupting its architecture. Optical Coherence Tomography (OCT) is crucial for identifying EIFL, which appears as a hyperreflective band within […]

Choroidal folds: Hypotony
62yoChoroidal folds are alternating light and dark bands on the retina caused by undulations in the choroid, Bruch’s membrane, and retinal pigment epithelium (RPE). Hypotony is a common cause, often following ocular surgery or inflammation. Clinically, folds appear as horizontal or oblique striations in the posterior pole. Diagnosis involves Optical […]

Choroidal nevus
55yoChoroidal nevus is a benign pigmented lesion that can be evaluated using fundus autofluorescence (FAF). Most nevi appear hypoautofluorescent due to their dense pigmentation blocking autofluorescence. However, areas of hyperautofluorescence may indicate overlying retinal pigment epithelium (RPE) changes, such as lipofuscin accumulation, which could signal an increased risk of malignant […]

Choroidal melanoma
72yoChoroidal melanoma can cause serous retinal detachment due to fluid leakage from the tumor or associated vascular abnormalities. Fundus examination typically reveals a dome-shaped or mushroom-shaped lesion with overlying retinal elevation. In selected cases, brachytherapy is used to preserve some vision and avoid more invasive, vision-threatening surgical procedures. #ChoroidalMelanoma #SerousRetinalDetachment […]

Choroidal rupture
15yoChoroidal rupture caused by blunt trauma often presents as a crescent-shaped tear in the choroid, Bruch’s membrane, and retinal pigment epithelium (RPE). Subretinal hemorrhage is commonly associated, complicating visualization of the rupture. Optical Coherence Tomography (OCT) and fundus imaging are crucial for identifying the rupture and assessing the extent of […]

Sclopetaria chorioretinopathy
65yoSclopetaria is a traumatic chorioretinopathy caused by blunt or projectile trauma, leading to retinal and choroidal damage. On fundus autofluorescence (FAF), sclopetaria shows hypoautofluorescence corresponding to areas of retinal pigment epithelium (RPE) loss and scarring, often surrounded by zones of hyperautofluorescence indicating RPE stress. FAF helps in assessing the extent […]

Lamellar Hole-Associated Epiretinal Proliferation
70yoLamellar Hole-Associated Epiretinal Proliferation (LHEP) is characterized by a unique epiretinal material associated with lamellar macular holes. Optical Coherence Tomography (OCT) shows a thick, homogenous, and moderately reflective epiretinal layer overlying the hole. LHEP is thought to arise from Müller cell proliferation and can influence surgical outcomes in lamellar hole […]

Congenital Hypertrophy of the Retinal Pigment Epithelium
29yoCongenital Hypertrophy of the Retinal Pigment Epithelium (CHRPE) appears as a flat, highly pigmented lesion on fundus examination. On fundus autofluorescence (FAF), CHRPE typically shows hypoautofluorescence. This imaging modality helps confirm the diagnosis and monitor for changes over time. #CHRPE #FAF #Hypoautofluorescence #RetinaImaging #PigmentedLesion #retina #oftalmo #ophthalmology #oftalmologia #oftalmología #ophtalmologie […]

Glaucoma: RNFL deffect
74yoIn glaucoma, retinal nerve fiber layer (RNFL) defects can be detected using the blue light reflectance in color fundus imaging as an alternative to Optical Coherence Tomography (OCT) Nerve Fiber + Ganglion Cell Deviation Map. The blue channel enhances contrast in the RNFL, making defects more visible by highlighting the structural […]

BRVO and asteroid hyalosis
89yoBranch Retinal Vein Occlusion (BRVO) and asteroid hyalosis can coexist, posing challenges in retinal imaging. Asteroid hyalosis, characterized by calcium-lipid deposits in the vitreous, can obscure fundus details. #BRVO #AsteroidHyalosis #RetinaImaging #OCT #FA #RetinalVeinOcclusion #retina #oftalmo #ophthalmology #oftalmologia #oftalmología #ophtalmologie #офтальмологія #офтальмология #οφθαλμολογία #retinography2024 #CIRRUS6000 #CLARUS700 #ZEISSRETINAWORKFLOW

Ocular toxoplasmosis
69yoA retinochoroiditis scar from toxoplasmosis is a hallmark lesion, appearing as a well-demarcated, atrophic area of retinal and choroidal tissue. It typically presents with a pigmented border surrounding a pale center, indicating previous inflammation. Optical Coherence Tomography (OCT) shows retinal thinning and disruption, while fundus imaging aids in monitoring for […]
